The ALPHA OPTICS 6015 multipurpose night vision monoculars are an outstanding choice for professional and commercial applications. Based on the ALPHA OPTICS PVS-14, the ALPHA OPTICS 6015 NVM has the highest quality in optics, design, and functionality. Each is a complete unit, including an image intensifier tube, a protective and generally water-resistant housing, compatible with different types of mounting systems. A built-in IR illuminator makes it possible to use the unit in low light or total darkness. LED lights indicate low battery and show the user that the IR illuminator is on. When co-aligned with a red-dot type sight on a Picatinny rail the monocular becomes an integral part of a formidable night vision weapons sighting system. With auto gain control, the device uses a sensor to automatically adjust the brightness level to provide the best view based on your ambient lighting conditions. The most versatile night vision systems on the market, it can be handheld, or head/helmet-mounted for hands-free use, or attached to a camcorder or a camera for nighttime photography. Designed for the most demanding nighttime military or law enforcement operations, it is also available for a wide range of applications for civilian users.
